FWIW:
I'm using a Zen MK III and the new firmware has a beta feature where you can use the Zen as an LMS within the Roon interface (Squeezelite emulation).
This is not a supported configuration, but I have been able to run the Zen in this configuration and upsample to DSD 64 using Roon DSP with few issues. Typically the processing speed is between 2-3x.
The few issues are stuttering/crashing if I skip ahead a track on a song without first stopping the song I'm listening to. I'm ok to live with that as the SQ is quite an improvement to my ears, but it could be a dealbreaker for some.
I can run the LMS within Roon/SqueezeLite WITHOUT DSD upsampling (disabling DSP) and have no issues whatsoever on the MK III.
I'm not sure what you are using DSP for if you are not doing upsampling, but it is true that DSD upsampling is the most memory-intensive operation. EQ and headroom probably would not cause as many issues as the upsampling to DSD 64.
